The first heat dissipating portion 1311 is at least partially disposed between the first case portion 111 and the second case portion 112. Specifically, the first heat dissipating portion 1311 is at least partially disposed inside the first receiving space S between the first case portion 111 and the second case portion 112 and passes through the two first lateral windows O1, O2, i.e., a first end of the first heat dissipating portion 1311 and a second end of the first heat dissipating portion 1311 opposite to the first end of the first heat dissipating portion 1311 respectively protrude out of the two first lateral windows O1, O2. The second heat dissipating portion 1312 is integrally connected to the first end of the first heat dissipating portion 1311. The third heat dissipating portion 1313 is integrally connected to the second end of the first heat dissipating portion 1311.

A height of the first accommodating space 1116 along the first direction D1 can be equal to a height of the second accommodating space 1127 along the first direction and greater than a height of the first receiving space S along the first direction D1. However, the present invention is not limited to this embodiment. The shape of the first heat dissipating component and the heights of the first accommodating space, the second accommodating space and the first receiving space along the first direction can be determined according to practical demands.
Furthermore, in this embodiment, the electrical receptacle connector 1 can be an optical communication connector, and the first contact set 121 and the second contact set 122 can be two optical communication contact sets. However, the present invention is not limited to this embodiment. For example, in another embodiment, the electrical receptacle connector can be an electrical communication connector, and the first contact set and the second contact set can be two electrical communication contact sets.
In addition, the electrical receptacle connector 1 further includes a covering body 14, a finger device 15 and a clipping component 16. The covering body 14 is connected to the case device 11 and at least partially covers the terminal device 12. Two opening portions 151 are formed on the finger device 15 and respectively located at positions corresponding to the first case portion 111 and the second case portion 112. The finger device 15 is assembled with the case device 11 along an inserting direction I and for preventing an electromagnetic interference. The clipping component 16 is for engaging with the second case portion 112, and the second heat dissipating component 132 is clamped by and located between the clipping component 16 and the case device 11.
The first contact set 121 and the second contact set 122 can be two receptacle contact sets in accordance with Universal Serial Bus (USB) specification. A first electrical plug connector 21 and a second electrical plug connector 22 can be two electrical plug connectors in accordance with Universal Serial Bus (USB) specification. However, the present invention is not limited thereto.
As shown in FIG. 3 to FIG. 6 , a first slot structure 1111 is formed on the first case portion 111. A first abutting structure 13111 is formed on the first heat dissipating portion 1311 and at least partially passes through the first slot structure 1111. A second slot structure 1121 is formed on the second case portion 112. A second abutting structure 1321 is formed on the second heat dissipating component 132 and at least partially passes through the second slot structure 1121. The first abutting structure 13111 can abut against the first electrical plug connector 21 for conducting heat generated by the first electrical plug connector 21 to the first heat dissipating portion 1311 by the first abutting structure 13111. The second abutting structure 1321 can abut against the second electrical plug connector 22 for conducting heat generated by the second electrical plug connector 22 to the second heat dissipating component 132 by the second abutting structure 1321.
In this embodiment, the first abutting structure 13111 and the second abutting structure 1321 can be two protruding platform structures. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first abutting structure 13111 or the second abutting structure 1321 can be a plate-shaped structure or a column-shaped structure.
As shown in FIG. 3 to FIG. 5 , in order to allow the first heat dissipating portion 1311 and the second heat dissipating component 132 to dissipate the heat conducted from the first electrical plug connector 21 and the second electrical plug connector 22 to the air rapidly, a first heat dissipating structure 13112 is further formed on the first heat dissipating portion 1311 and for increasing a heat dissipating area of the first heat dissipating portion 1311, and a heat dissipating structure 1322 is further formed on the second heat dissipating component 132 and for increasing a heat dissipating area of the second heat dissipating component 132.
In this embodiment, the first heat dissipating structure 13112 and the heat dissipating structure 1322 can be two thermal fin structures, such as two plate-fin structures. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first heat dissipating structure or the heat dissipating structure can be a column-fin structure.
As shown in FIG. 4 to FIG. 5 , the first case portion 111 and the second case portion 112 not only abut against the first electrical plug connector 21 and the second electrical plug connector 22 respectively but also abut against each other. Therefore, the heat generated by the first electrical plug connector 21 and the second electrical plug connector 22 can be conducted to the second case portion 112 directly and/or indirectly. In order to avoid heat accumulation, at least one heat dissipating abutting structure 1122 is formed on the second case portion 112 and abuts against the first heat dissipating structure 13112, so that the heat conducted to the second case portion 112 can be conducted to the first heat dissipating structure 13112 by the heat dissipating abutting structure 1122.
In this embodiment, the heat dissipating abutting structure 1122 can be a resilient arm structure. However, the present invention is not limited to this embodiment. For example, in another embodiment, the heat dissipating abutting structure can be a protruding lug structure.
Understandably, the number and the configuration of the heat dissipating abutting structure are not limited to those illustrated in the figures of this embodiment. It depends on practical demands.
Besides, as shown in FIG. 1 to FIG. 4 , the first end and the second end of the first heat dissipating portion 1311 are integrally connected to the second heat dissipating portion 1312 and the third heat dissipating portion 1313 respectively, which results in a low heat resistance between the first heat dissipating portion 1311 and the second heat dissipating portion 1312 and a low heat resistance between the first heat dissipating portion 1311 and the third heat dissipating portion 1313. Therefore, the heat conducted to the first heat dissipating portion 1311 can be rapidly conducted to the second heat dissipating portion 1312 and the third heat dissipating portion 1313. Furthermore, in order to allow the second heat dissipating portion 1312 and the third heat dissipating portion 1313 to dissipate the heat to the air rapidly, a second heat dissipating structure 13121 and a third heat dissipating structure 13131 are respectively formed on the second heat dissipating portion 1312 and the third heat dissipating portion 1313 and for increasing a heat dissipating area of the second heat dissipating portion 1312 and a heat dissipating area of the third heat dissipating portion 1313.
In this embodiment, similar to the first heat dissipating structure 13112 and the heat dissipating structure 1322, the second heat dissipating structure 13121 and the third heat dissipating structure 13131 can be two thermal fin structures, such as two plate-fin structures. However, the present invention is not limited to this embodiment. For example, in another embodiment, the second heat dissipating structure or the third heat dissipating structure can be a column-fin structure.
Specifically, as shown in FIG. 3 to FIG. 5 , the first case portion 111 includes a first wall 111A, a second wall 111B, a third wall 111C and a fourth wall 111D. The first wall 111A and the second wall 111B are located opposite to each other. The third wall 111C and the fourth wall 111D are located opposite to each other and connected to the first wall 111A and the second wall 111B. The first wall 111A is located adjacent to the first heat dissipating portion 1311. The first slot structure 1111 is formed on the first wall 111A. The third wall 111C is located adjacent to the second heat dissipating portion 1312. The fourth wall 111D is located adjacent to the third heat dissipating portion 1313. The second case portion 112 includes a fifth wall 112A, a sixth wall 112B, a seventh wall 112C and an eighth wall 112D. The fifth wall 112A and the sixth wall 112B are located opposite to each other. The seventh wall 112C and the eighth wall 112D are located opposite each other and connected to the fifth wall 112A and the sixth wall 112B. The fifth wall 112A is located adjacent to the second heat dissipating component 132. The second slot structure 1121 is formed on the fifth wall 112A. The seventh wall 112C is located adjacent to the second heat dissipating portion 1312. The eighth wall 112D is located adjacent to the third heat dissipating portion 1313. The heat dissipating abutting structure 1122 is formed on the sixth wall 112B.
In addition, as shown in FIG. 3 to FIG. 5 , a thickness of the first heat dissipating portion 1311 along the first direction D1 is greater than a thickness of the second heat dissipating portion 1312 along a second direction D2 and greater than a thickness of the third heat dissipating portion 1313 along the second direction D2. A length of the first heat dissipating portion 1311 along the second direction D2 is greater than a length of the case device 11 along the second direction D2. The thicker first heat dissipating portion 1311 can absorb more heat and conduct the heat to the thinner second heat dissipating portion 1312 and the thinner third heat dissipating portion 1313 located outside the case device 11 rapidly. Therefore, the first heat dissipating component 131 has enhanced heat dissipating performance. Preferably, the first direction D1 can be perpendicular to the second direction D2, and the first direction D1 and the second direction D2 can be perpendicular to the inserting direction I of the first electrical plug connector 21 and/or the second electrical plug connector 22.
Understandably, the sizes of the first heat dissipating portion, the second heat dissipating portion and the third heat dissipating portion are not limited to this embodiment. It depends on practical demands.
As shown in FIG. 3 to FIG. 6 , at least one first engaging structure 1112 is formed on the first case portion 111. At least one second engaging structure 1123 is formed on the second case portion 112. The second case portion 112 is detachably assembled with the first case portion 111 by an engagement of the at least one second engaging structure 1123 and the at least one first engaging structure 1112. When the second case portion 112 is detachably assembled with the first case portion 111, the first case portion 111 and the second case portion 112 can cooperatively form the first receiving space S, which is shown in FIG. 6 , for at least partially accommodating the first heat dissipating portion 1311.
In this embodiment, the first engaging structure 1112 can be a protruding structure. The second engaging structure 1123 can be a notch structure. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first engaging structure and the second engaging structure can be an engaging protrusion and an engaging recess.
Understandably, the numbers and the configurations of the first engaging structure and the second engaging structure are not limited to those illustrated in the figures of this embodiment. It depends on practical demands.
Specifically, the third wall 111C and the fourth wall 111D do not protrude out of the first wall 111A. The seventh wall 112C and the eighth wall 112D protrude out of the sixth wall 112B. The first receiving space S is defined by the first wall 111A, the sixth wall 112B, the seventh wall 112C and the eighth wall 112D. The seventh wall 112C does not contact with the third wall 111C, so that the first lateral window O1 is defined between the seventh wall 112C and the third wall 111C and for allowing the first end of the first heat dissipating portion 1311 to pass therethrough. The eighth wall 112D does not contact with the fourth wall 111D, so that the first lateral window O2 is defined between the eighth wall 112D and the fourth wall 111D and for allowing the second end of the first heat dissipating portion 1311 to pass therethrough.
As shown in FIG. 3 to FIG. 6 , the first engaging structure 1112 and the second engaging structure 1123 are respectively located at a rear side of the first case portion 111 and a rear side of the second case portion 112. Therefore, in order to increase an overall structural strength, a first supporting structure 1113 is formed on the first case portion 111. A second supporting structure 1124 is formed on the second case portion 112. When the second case portion 112 is detachably assembled with the first case portion 111, the first supporting structure 1113 and the second supporting structure 1124 abut against the second case portion 112 and the first case portion respectively. The first supporting structure 1113 and the second supporting structure 1124 are respectively located at a front side of the first case portion 111 and a front side of the second case portion 112 for positioning the front side of the first case portion 111 and the front side of the second case portion 112. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first supporting structure 1113 and/or the second supporting structure 1124 can be omitted.
Furthermore, in order to make sure that the front side of the second case portion 112 and the front side of the first case portion 111 are not displaced, at least one first positioning structure 1114 is formed on the first case portion. At least one first positioning portion 11241 is formed on the second supporting structure 1124. At least one second positioning structure 1125 is formed on the second case portion 112. At least one second positioning portion 11131 is formed on the first supporting structure 1113. When the first supporting structure 1113 and the second supporting structure 1124 respectively abut against the second case portion 112 and the first case portion 111, each first positioning structure 1114 and each second positioning structure 1125 respectively pass through and engage with the corresponding first positioning portion 11241 and the corresponding second positioning portion 11131 for positioning the first case portion 111 and the second case portion 112.
Furthermore, a plurality of snapping portions 141 are formed on the covering body 14. At least one first snapping structure 1115 and at least one second snapping structure 1126 are respectively formed on the first case portion 111 and the second case portion 112. The first snapping structure 1115 and the second snapping structure 1126 are used to be engaged with the corresponding snapping portions 141 for achieving assembly of the covering body 14 and the case device 11.
In this embodiment, when it is desired to assemble the electrical receptacle connector 1, a user can stack the first case portion 111, the first heat dissipating portion 1311 and the second case portion 112 along the first direction D1 sequentially and respectively engage the first engaging structure 1112, the first positioning structure 1114 and the second positioning structure 1125 with the second engaging structure 1123, the first positioning portion 11241 and the second positioning portion 11131, so as to achieve assembly of the first heat dissipating component 131 and the case device 11. Afterwards, the user can assemble the covering body 14 with the case device 11 by an engagement of the first snapping structure 1115 and the snapping portion 141 and an engagement of the second snapping structure 1126 and the snapping portion 141, and then assemble the finger device 15 with the case device 11. After the covering body 14 and the finger device 15 are assembled with the case device 11, the user can place the second heat dissipating component 132 on the fifth wall 112A of the second case portion 112 and then engage the clipping component 16 with the case device 11 to clamp the second heat dissipating component 132 by the engagement of the clipping component 16 and the case device 11. From the above, the electrical receptacle connector 1 has an advantage of easy assembly.
